Here's a good few I'd like to catch...
Atlantic Salmon... George River.
Tarpon... Boca Grande, Rio San Juan, Barra Del Colorado.
Giant Trevally... Seychelles
Steelhead... anywhere West Coast.
Taimen... Mongolia
Peacock Bass... Brazil
Yellowfiin... say... Cabo
Some notables... grouper, lake sturgeon, gar, striped bass, bonefish, inconnu, yellowfin, shark, halibut, tiger trout and aurora trout.
Would like to tangle with another marlin, but not one 400+ pounds... about 150 would be perfect. Like to catch more sailfish and sturgeon.
I'd give up every other fish for a lifetime of arctic char in Coronation Gulf and the Tree. Not a week goes by the Tree doesn't come to mind.
